PAPER CLIP.

Application led April 24, 1923. Serial No. 634,243.

My invention relates to` improvements in paper clips of the type knowngenerally as Gein clips and it has for its) eneral ob ject to provide aclip in which t e portlons a ci the surfaces which are adapted to con-'tact with the sheets of paper or other lilre` ilu 'lully appreciatedreference may be had to.

the accompanying `drawings in which I have illustrated the invention asembodied in a number of clips.

ln the drawing: Q lfig. 1 is a view in side elevation cfa wire providedwith oppositely disposed notches therein which notches extendat rightangles across the said wire;'

lllll Fig., 2 is a longitudinal sectional View o` au `the wire taken atright angles to the said notches;y

Fig. 3 is a plan view of a paper clip con structedof alsection of thewire shown in Figs. 1 and 2;

Fig. 4 1s a v1ew in side elevation looking toward the left in Fig. 3;

Fig. 5 is a plan view of a paper clip showing the notches in the wireextending at an acute angle thereto;

Fig. 6 is a view in side elevation of a ortion of the wire of the clipshown in ig. 5; v

Fig. 7 is a view in plan of a portion of wire showing the notchescrossing each othia er;-and

Fig. 8 is a view showing a still further modification of the structurein which the' notches upon one side of the wire are extended in onedirection while thoseuponI thc au opposite side are extended incrosswiserelation thereto. y

Referring to the drawing: 1 desi ates a wire of indefinite orundetermined en'gth provided with notches 2 arranged at inter- 56 valsthereon. These notches are Vprovided upon opposite sides of the wire inopposed fgsaid clips `to rmly hold a plurality' of -sheets lo 4cated at13` and 14. The extendedfportion '13 is connected with the portion 1 0by means relation to each other, as shown. The said notches may beproduced in any, suitable manner and by any suitable means but I havefound that they may be most economically and elciently producedbypassing the wire between a couple of oppositely disposed and co-actingknul-led rollers. After a wire has been notched eitherv as indicated inFigs. 1 and2`or otherwise it is cut into sections as indicated by thedash and dot lines 3 in Fig. 1 which sections are subsequentlyv bent toform clips ofthe character shown in planin Figs. 3 and 5 ot the drawing.

In the formation of the notches in the wire the metal upon oppositesides of the notch is slightly expanded, as indicated" at 5, so as toform slightly elevatedor projecting portions upon the opposite sides ofthe notches. The presence of ysuch elevations and notches in thesections of wirel frein1 which the clips are constructed causes thepaper or the like upon which the B0 said clips may be placed.

In Figs. 3 and L1 of the drawing I have shown a clip constructed ofwir-erin whichV the notches are of the character `illustrated inv Figs.1 and 2; that is to say,'the notches extendatright angles to the lengthof' the wire. In the vmanufacture of the clips from wire sich asis shownin Figs. 1 and 2 such wire is cut into short lengths o r sections, asabove indicated, which sections are-bent to form a U-shaped portion 9having parallel legs 10 and 12. The end portions of these legs are bentand extended, as indies of a bend, as indicated at 15while the extendedportion '14 is' connected with the part 12 by meansof abend, asindicatedy at 16. The bends 15 and 16 are spaced from lm l each other asindicated and may lbe described as being concentric with respect to eachother.- The extended portion 13 is located inside of the portion 12 andin parallel relation thereto. It is situated between -thepor tions 10and 12. The extended portion 14 is situated outside of ,and in Yparallelrelation to the ortion 10. The" portions 13 and 14 are lustrated asbeing in contact respectvelywith the portions 12nd 10,

but such contact relationship is tial to the invention.

are of such character that they ho U-shaped portions which are connectedtogether by the bend which connects the portions 10 and 12 together. Thesaid U-shaped portions formed in the'opposite end portions of the wireconstitute the holding portions of the fastener.

Referring nowto Fi s. 5 and '6 it will be observed that the notc es 18are arranged at an inclination with respect to the length ofthe wire;that is to say, at acute angles with respect to the said Wire. The clip,as shown in Fig. 5, is provided with the ortions 10, 12, 13, 14, 15 and16 correspon ing to the parts similarly designated in Fig. 3 of thedrawing.

In Fig. 7 I have shown a construction in which the notches 20 and `21arearranged in couplesupon opposite sides of the wire and'in which thenotches of each couple cross each other, as indicated. I have shown thevnotches only upon one side of the wire but it will be understood thatsimilar notches construction in which the notches 22 and 23` arearranged at intervals singly upon op- .posite sides of the wire and atangles to each other. In the construction as shown the notches 22 uponthe top sides of the wire which are shown in .full lines are arranged atan angle of substantially ninety degrees with respect to the` notches 23shownl in dotted lines upon the opposite side of the It will be seenfrom the foregoing that the notches may be arran ed in almost any manneras may be desi or preferred. It will also be seen that byreason of theexpansion of the material in the formation of the notches immediateladjacent the opposite sides ofthe same t e gripping surfaces of theportions of the wire constituting the clip l securely and eiciently thesheets which may be placed between the holding parts of the clips.

It will also be seen that the notches are provided continuousl alo oposite surfaces' of thev wire o whic -t e clips are produced so that inthe completed clips the notches are provided upon all portions thereofthereby rendering more efficient the action of the clips in holding anumber of sheets upon which the said clips ma be laced.

It will be noted further t at tie notches and slight elevations upon oposite sides of the wire of a clip are arran ed in diametf ricallyopposed relation to eac other. This arrangement is preferred because ithas been found that by arranging the notches and the slight elevationsof the metal upon opposite sides thereof in opposed relation to eachother they co-operate more directly with each other an therefore aremore eicient in their action in holding a number of sheets of paper`which may be laced therein.

Although it is preferred that the notches shall be provided uponopposite sides of the wire of which the clip 1s constructed, as

vshown in the drawing, yet if desired the clips may be made of wirehaving notches only on one side thereof.

Having thus described my invention, what I claim and desire to secure byIfetters Patent is: y

1. A paper clip comprising a section of wire, the opposite ends of whichterminate in U-shaped portions the intermediate portion of the said wirehein bent to U-shape so as to locate the said -shaped o'rtions in nestedand operative relation with respect to each other, and the wire of thesaid clip being provided with notches upon its op posite sides whichnotches extend at an inclination with respect to the length of the saidwire.

2. A paper clip comprisin a'section of wire, the o posite ends of w ichterminate in U-sha e portions, the intermediate portion of t e said wirebeing bent to U-shape so as to locate the said U-sha d portions innested and operative relation with respect to each other, and the wireof the said c ip being provided with groups of notches arranged atintervals on opposite sides thereof, the notches of each group extendingat angles with respect to each other. l

In testimony that I claim the foregoing as my invention I have hereuntosigned my name this 18 day1 of April, A. D., 1923.
